Google provides a number of templates that you can use to form the basis of your spreadsheets. You can create a new sheet based on a template, then edit the sheet as required.
To create a sheet based on a template:
From the Google Drive screen, click on the New button.
Choose Google Sheets, then From a Template
From an existing sheet, click on the File menu, choose New, then From template
Choose the General tab for standard Google templates, or your domain tab for custom templates for your organisation. Click on the template you wish to use to create a new sheet based on that template.
Once the new sheet has been created, you can name the sheet by double-clicking on the sheet name and typing a new name.
